REVERSIBLE WlNDOW-SASH.

SPECIFICATION forming part of Letters Patent No. 425,146, dated April 8, 1890. Application filed October 26,1889. Serial No.328,296. (No model.)

To to whom it may concern:

Be it known that we, ERNEST L. REGUIN, of the city of Sacramento, in the county of Sacramento, State of California, and THOMAS J. KINGSTON, of the city and county of San Francisco, State aforesaid, have invented an Improvement in Reversible VVindow-Sashes; and we hereby declare the following to be a full, clear, and exact description thereof.

IO Our invention relates to that class of window-sashes which are pivoted by their stiles to the casing, whereby they are adapted to be reversed in order to allow the outside of the glass to be reached and cleaned with convenience.

Our invention consists in the novel con struction and arrangement of the sash-frame, the means for turning the sash and looking it in position when turned, the means for tight- 26 ening' it, and other details of construction,

, hereinafter fully described, and specifically pointed out in the claims.

Referring to the accompanying drawings, Figure 1 is an elevation of a window frame and sash, a portion of one side being broken away and shown in section. Fig. 2 is a horizontal section. Fig. 3 is a vertical section of a portion of the sash-frame, slide-bar, and

bearing-plate F.

A is the usual casing of a window, having the inside and outside stops or beads to and the parting-strips a.

B is the window-sash, and C are independent slide-bars, which intervene between the 3 5 stiles b of the sash and the grooves of the window-casing. The sash-stiles b are formed with slight tongues b and the adjacent faces of the slide-bars C are formed with corresponding grooves 0, so that the two fit together by a tongue-and-groove joint. Secured to the sash-stiles on each side at about their centers are the pivot-pins D. These are securely fastened to the stiles, and they pass through holes 0 in the slide-bars, whereby the sash-frame 5 is pivoted to said slidebars and may be turned between them, In the pivot-pins is made an encircling groove (1 and a second encircling groove (1. These grooves, though they may be formed in any suitable manner, are preferably formed in the shape of a double cone, as shown, whereby they have beveled surfaces adjacent to one another, thereby allowing them to slip by the set-screws, when loosened, with facility.

In the slide-bars C are seated the set-screws 5 5 E, the inner ends of which are adapted to bear within either of the grooves of the pivotpins. Fitted upon the ends of the pivot-pins are the bearing-plates F, which rest against a shoulder d on said pins, so as to hold them out to place in constant contact with the bottom of the window-casing grooves. These plates extend out beyond the back surface of the slide-bars and bear constantly in the bottoms of the grooves of the windowcasing. They are separated from the slidebars sufficiently to permit the latter to have their necessary side movement to or from the sash-frame. This separation may be effected in any suitable manner, though in order to have the slide-bars fit the casing as snugly as may be consistent with their side movement we prefer to seat the bearingstrips partially in chambers 0 made in the back surface of the slidebars, said chambers being large and 7 5 deep enough to freely fit and play over the bearing-strips as the bars are moved in and out.

G are frictional binding-strips, which are pivoted to the slide-bars at their upper and lower ends, the ends of said strips being turned at right angles and adapted to bear against the window-casing, being held in this position by their other ends fitting by means of a small holeg over a small pin or stud g '85 in the slide-bar.

The construction will be better understood by describing the operation of the windowsash, which is as follows: hen the sash is in its place in the window-casing, the slidebars 0 are moved up close to the stiles of the window-sash, so as to make a tight tongueand-groove joint therewith, and they are held firmly in this position by means of the setscrews E, which are turned in so as to bind 9 5 tightly in the first groove of the pivot-pins D.

In this position it is obvious that the sash cannot be released from the slide-bars, as the tongue-and-groove jointbetween them holds them together. Consequently, the slide-bars loo must be moved out sidewise away from the sash in order to relieve the sash of the ton gueand-groove joint. The construction, therefore, must be such to allow the slide-bars suflicient side play in the wiinlomframe to free the sash; but in allowing this side play it is necessary that some bearingbe provided, so as to constantly hold the entire sash closely in the window-casing and prevent it from wabbling. This resultis effectedhy the bearing-plates F on the ends of the fixed pivotpins D, which, as before stated, project beyond the back surface of the slide-bars and lit directly and constantly against the bottoms of the grooves of the window casing, thereby holding the entire device snugly in its seat. Now, in order to reverse the window-sash the set-screws E are turned back, so as to free their inner ends of the groove of the pivot-pins D. Then both slide-bars are moved bodily sidewise on the pins away from the stiles of the sash until the tongue-andgroove joint is broken, whereby the sash may be readily turned, its pivot-pins turning in the slide-bars. This movement of the slidebars is on the fixed pivot-pins, their chambers c in their back surfaces playing freely over the stationary bearing-strips 1*, which do not interfere with the movement of the slidebars. \Vhen the window is turned to any position desired, it can be held in that position by turningin the set-screws again, so that they fit theirends into the second grooves of the pins.

The weights \V are suspended by cords m, which are attached to the slidc'bars of the windmv-sash. The object of the frictional binding-strips G is not only to prevent any looseness in the sash, but also, by hearing against the window-easing, to hold with greater security the slide-bars and the stiles of the window-sash together.

\Ve are aware that wiinlow-sashes have been pivoted on each side,whereby they are adapted to be reversed, and we are also aware that slide-bars have been mounted in the grooves of the window-casing, and to these bars the sash-frame proper has been pivoted, and we do not, therefore, claim such, broadly; but

\Vhat we do claim as new, and desire to secure by Letters Patent, is-

1. In combination with a window-frame having the usual grooves, the windowsash having fixed to its sides the pivot-pins l), the independent and .laterally-movable slide-bars fitted and movable upon the pivot-pins of the sash and seated in the grooves of the windowcasing, and set-screws in the slide-bars bearing upon the pivot-pins of the sash, whereby the movable slide-bars may be held to the sash and the sash itself held in any position to which it is turned, substantially as described.

2. In a reversible window-sash, the combi nation of the sash-frame having the fixed. side pivot-pi us, the independent and laterallymovable slide-bars seated in the window-casing grooves and fitted and movable upon the side pins of the sash-frame, a tongue-andgroove joint between the slide-bars and the sash-frame, and set-screws in the slide-bars bearing on the pins of the sash-frame, whereby the bars and frame are held together and the sash-frame held in any inclination to which it may be turned, substantially as described.

3. In a reversible window-sash, the combination of the sashfra-mehaving the fixed pivotpins extending from its sides, said pins having the two encircling grooves, the independent and laterally-movable slid e-bars seated in the grooves of the window-casing and fitted and movable upon the pins of the sash-frame, the tonguc-aml-groove joint between the stiles of the sash-frame, and the slide-bars and the set-screws in said slidebars for bearing in either of the grooves of the pivot-pins, where by the slide-bars are held to the stiles and the sash-frame held at any inclination to which it may he turned, substantially as described.
